The electric drill is one of the most versatile repair tools. By changing drill bits, you can make holes in plastered walls, pipes, wood and metal. Protect your valuable tool from wear and tear by changing drill bits to the right one for each material. Determine if you need a chuck wrench to loosen the drill bit clamp, then do so and remove the drill bit. Take care of your drill and drill bits to extend the life of your tool.
Pull out the drill bit. When you loosen the chuck clamp, the drill bit in the slot will start to wiggle. You can effortlessly pull it out of the slot.  X
Always keep an eye on the drill bit when you remove it from the chuck. If a drill bit is damaged or excessively worn, it is time to discard it to avoid installing it later by mistake.
- Continue to hold the drill bit in the chuck in position as it is not yet locked in place and could fall out or fall in deeper than necessary.
Pull the trigger. Secure the drill bit in the chuck by pressing the trigger on the drill a few times for a split second. Hold the drill with your other hand lightly until the drill bit is held firmly by the clamping jaws.  X Source of information
Hold the drill lightly while you turn the drill on in short bursts so that it locks evenly.
If necessary, use a ratchet tightening mechanism. If your drill has a ratchet mechanism to hold the drill rod, attach it to the drill. To do this, turn the ratchet mechanism next to the clamp clockwise.  X
- Many drills with a chuck wrench have a mount where that wrench will be safely stored.
- Drills that are plugged in usually have a chuck wrench, not cordless drills.
Turn the chuck wrench counterclockwise. As you turn the wrench, the chuck jaws will open. Continue turning the wrench until the drill comes out of the slot easily.
Clamping cams are three or four pieces of metal inside the chuck that split apart and squeeze together to hold the drill in place.
- Inspect the drill that you just pulled out. Check it for damage and worn parts. If the drill bit is dull, it is worth replacing it. If the drill bit is bent or even cracked, throw it away to avoid using it again by mistake.
How to Insert the Drill Bit
Lubricant for the drill bit
In order for this process to go smoothly, it is important to follow some consistent steps:
- Make sure the drill is unplugged before you put the drill in the chuck.
- Then insert the drill bit into the chuck. To do this, first make sure that the drill bit used is for the specific tool.
- To reduce chuck wear on the drill bit, you can lubricate the drill bit with a special grease. You can apply it to the chuck hole.
- Next, attach the drill bit.
- Once the drill bit is in the chuck, it is important to make sure that it does not wobble.
Do not touch the rotating parts of the drill or the rotary table during drilling. As you can see, inserting the drill bit is no problem at all.
It all depends on the chuck you use. But what to do, if after work it is not possible to extract the drill from the chuck?
How to Insert the Drill Bit into the Drill Bit: Basic Requirements
Table of contents: A little bit of unspecialized information Drill chuck How to stick the drill: the main requirements Drill installation in a drill with a quick-action chuck Drill installation in the main chuck Drill chuck is a necessary household and widespread tool. Every person faces the moment when he first decided to use it, and first remembers how to put the drill bit in the drill.
Drill bit structure diagram. It is true, it is unrealistic to use it without solving the problem.
The answer to this problem is not a huge problem, but when using the tool for the first time it is better to consult. An improperly inserted drill bit can cause a great deal of unnecessary trouble.
Little specified information Drill types. A drill is a tool for drilling holes.
Varieties can include a peorator and an electric screwdriver. In all constructions, the motion of the working element is transferred from the power source through a chuck in which the working element is fixed.
For drills, the tool is used, which is a cylindrical iron rod. It is made up of three parts. The working part, the neck and the shank.
To fix helps shank, which can vary in shape of their own cross-section (circle, triangle, quadrangle). As a rule, tools with a round shank are used.
Drills have different diameters and length of shank and working part. Return Drill chuck Drill chuck design. Most household tools contain a cam-type chuck.
Such components are made in the form of a cylindrical body, on the surface of which the adjusting ring (sleeve) moves. In the cylinder there are cams, which due to the cone design of their surface come closer to each other when rotating ring in clockwise direction and recede when moving counterclockwise.
A shank is inserted in the gap between the jaws. Clamping jaws lock the tool in the chuck.
This chuck design allows fastening of work pieces with cylindrical shank of various diameters. Cam chucks for household drills are made with a standard range of drills clamped. 0,8-10 mm and 1,5-13 mm.
Chucks for household drills are made with two variants of clamping. Simple (main or gear-type) and quick-clamping. In the simple chuck, the adjusting ring is moved by a gear drive using a special key.
A metal sleeve with a knurled surface is used in the quick-action chuck to guide the jaws. Sleeve rotation is manual.
Locking or clamping elements can be used in the design of quick-action chucks to limit the tightening torque. In such cases, the end of the cutting element clamping is fixed by a click or triggering of a locking pin (button).

In addition, the cartridges can be singlecoupling or doublecoupling. In the first case, the regulating sleeve rotation is relative to the drill body and it is enough to fix it only.
In the second case, the sleeve moves rather a second sleeve (ring), which for its part can rotate relative to the body, which requires that the second sleeve be fixed by hand when rotating the sleeve. How to insert the drill bit: the main requirements for drill quality and working safety depends a lot on how to insert the drill bit into the tool and fasten it into the chuck.
A drill bit that is not well secured can fly out and cause injuries. The first requirement is therefore that the workpiece must be properly secured.
To do this, it is necessary to plunge it into the cartridge until it stops. It is not recommended to increase the length of the working part at the expense of incomplete insertion of the shank. If the diameter of the tool is not within the range of the guaranteed tightening, the tool must not be used.
The next condition is that the drill must be fixed axially in the drill. Any deviation of the drill from the axis will lead to poor quality drilling (overdrilled holes, deviation from round shape or curvature of the hole in the thickness of the product) due to the run-out.
Return Drill bit installation in a drill with a quick-action chuck Drill button connection diagram. Before inserting the drill into the drill, first check that the drill is working correctly, i.E. Е. Turn it on.
After that the drill chuck must be checked. For which, first of all, the tool must be de-energized. All work on the installation of the drill is carried out while the plug is unplugged from the power supply!
Manually, by turning the cartridge case counterclockwise, the cartridge jaws are set as far apart as possible; later, by turning the cartridge case clockwise, they are set as far apart as possible. Rotation must be light. If there are any difficulties, it is best to lubricate.
After the test, the cams must be set at a distance slightly larger than the diameter of the drill bit. Then the cutting element should be inserted into the chuck until it stops. Clamping the drill bit in the quick-clamp version is performed by rotating the sleeve clockwise by hand.
In this chuck the sleeve ring at the bottom (two-coupling version) or the drill itself (one-coupling version) can be fixed without moving with the other hand. Rotate the sleeve until the drill bit clicks or the latch clicks into place, if the drill bit is not available. As long as manual rotation at full hardening is possible.
Return Drill bit installation in the main chuck To install the drill bit in such a drill, the same work is done as for the quick-action variant. The difference is in the method of rotation of the adjusting sleeve.
In this type of chuck, there is a socket on the side of the sleeve for inserting a special wrench. The key should be inserted into the socket and turned clockwise as far as it will go to lock it.
After installation, you need to check (visually and manually) the location of the worker and the reliability of fastening of the element relative to the axis. After everything is done to put the drill in, the drill can be turned on and start working.
How to Insert a Drill Bit into a Peorator: Pro Tip
Take the drill bit and insert it into the drill chuck. Turn the upper part of the chuck clockwise as far as it will go. Check the drill for play. If the drill bit is loose enough, tighten the upper part of the chuck tighter. When finished, turn on the drill and give it an idle load, which gives the grease a chance to reach each part. This is the standard solution to the question of how to insert the drill bit into the drill chuck in a safe way.
How to insert a drill bit into a cordless drill
Not only are the peorators manufactured by Makita durable and practical in operation, but they can also be quickly opened when the need arises. Use an Allen key to unscrew the four screws and remove the plastic housing. It is so convenient and uncomplicated that there is no question how to disassemble the Makita torch in cases of repair and cleaning of its electric motor. Reassemble as quickly as you disassembled it, only in reverse order.
In principle, you can get to the gearbox by carrying out several disassembling operations. First remove the chuck, then remove the drill and chisel switch mechanism. And then it’s turn for the screws, which you can unscrew with an Allen key. They tighten the housing of the motor and the gearbox. As you can see, the task is not at all difficult, how to disassemble the Makita 2450.
If it is a peorator that promises a long and reliable life, then the choice should not fall on a drill sublimated with a peorator, but simply on a separate wall-piercing tool. As a rule, such a drill has a special adaptor included in the delivery set that allows working with it as a usual drill. That’s practically one main piece of advice on how to choose the right geared torch for your home.
To disassemble the cartridge of the peorator you need to open it as much as possible. There is a screw that unscrews exactly in the right direction (has a left-hand thread)
It happens that the screw does not come out, so use a hammer or blunt chisel to gently tap it and try to get it out again. The other way to disassemble the cartridge does not work
After removing the screw, the chuck will split into its component parts.
Every home has tools for drilling iron, wood, piercing brick and other material walls. Learn to work with a drill and a torch, and in the case of a minor breakdown reliably repair the tools themselves, should be able to every owner. Our material will help in this case to some extent. And also to choose in the store the peorator that is the most effective.
Drill bit for peorator: how to insert, remove, secure
With the advent of concrete reinforced structures, external and internal repairs can not be performed without a peorator. On the market there are a large number of models from different companies, these are Bosch, Makita, Sturm, Zubr, Vihr, Dexter, Interskol, Kalibr, Metabo, Soyuz. Despite the variety, the basic components and mechanisms work in much the same way. The process of re-installing the workpiece is also similar. Before inserting a drill bit into the peorator, you need to know how to get it out properly.
- What is a peorator?
- The tooling of the peorator
- Inserting the drill bit into the peorator
- How to remove the drill bit if the chuck is undamaged
- What to do if the drill doesn’t move out of place
- How to take the drill out of a damaged chuck
- What to do if the drill bit breaks
- Can a regular drill bit be inserted in the peorator?
What is a drill bit?
The peorator is a versatile tool and has many possibilities. It has a pneumatic device inside that pushes a piston in contact with the bit. The latter makes the tool reciprocate. As a result, the nozzles destroy any surface. The presence of the impact function allows the tool to drill holes in hard materials.
Its purpose depends on the integrated modes: drilling, chiselling, and drilling. A toggle switch is available for switching modes.
Producers produce models with different weight:
Power and impact force depend on the size of the torch.
Design of the torch
The tooling of the torch
It is most often used to work with:
Seldom in wood. The variety of materials implies a large number of attachments (working tool):
All of them are designed to perform different jobs. The drills precisely make holes of the required diameter and depth in the surfaces.
Products that are designed to work on such a durable material as concrete, are made with the use of carbide plates. They are soldered onto the cutting part. But they wear out in the course of use.
How to sharpen a concrete drill bit for a rotary hammer? Sharpening can be performed on a corundum-sharpening disc. Which is mounted on the corresponding equipment. The drill should be sharpened so that the worn cutting edges become straight, and the place where they intersect exactly coincides with the axis of rotation of the torch. You should also pay attention to the grinding angle of the two cutting edges. If this parameter is not uniform, the edge that has a large sharpening angle will be stressed more. The result will be a rapid failure of the torch.
Bits are designed to penetrate high-strength materials. A tool with a drill bit simultaneously drills, vibrates, or strikes. Such work is necessary when installing the socket. When a chisel or spade is mounted on the machine, it works like a jackhammer.
The type of attachment of all attachments, except for drills, is suitable only for peorator, because it has under it a groove-shaped attachment and a landing tail. An ordinary drill bit can be fixed in the rotary drill, but a removable chuck (adapter) is needed. It comes in 2 versions: cam-operated and quick-clamping. A special wrench is used to fasten the cam-operated clamp. It is inserted into the thread on the outer perimeter and turned. At this time the collet mechanism. Which is mounted inside the chuck, depending on which direction the wrench is moved, compresses or unclenches.
The quick-action chuck is actuated by applying a small amount of force by hand. The drill hole is opened by pushing down on the chuck.
There is also a small extended design that allows you to extend the drill bits. Thanks to the extension drill, it is possible to make deeper drill holes in various materials. When drilling with it, you have to adjust the cutting modes carefully.
Inserting the drill into the chuck
There is also a rapid-clamping mechanism on the tool itself. The drill in it is securely fixed with special balls, locking them tightly into the grooves that are on the bottom of the drill. The installation procedure looks simple. To fix the drill bit or the drill bit, the lower part of the chuck is pushed to the side (down) of the rotary table. Hold it in this position, install the required equipment and release the chuck. It happens that the balls are not included in the grooves, and as a result of the nozzle is moving, it is necessary to turn it until the design is completely closed.
If the drill bit has to be inserted into the peorator using an adapter, first the removable chuck with grooves for fastening to the tool must be installed and secured, and then the drill bit itself.
Before inserting or removing the drill bit into the Bosch peorator, it is absolutely necessary to check the condition of the tool. Then switch it on, set the necessary mode, press the start button. You can proceed to work, if there is no smell of burning plastic or burning, no unintelligible sounds.
The fixing device is a non-drilling chuck
The chuck is the fixture in which the drill is fixed. The fastener itself is screwed onto the tool spindle. Most drills are equipped with a cam-type chuck. This construction is a hollow cylinder with metal “fingers” inside. Turning the adjustment ring on the outside of the knot causes the “fingers” to bind or unbind on the tapered inside surface. Drill bits with a cylindrical or hexagonal shank can be fitted in this “jaw.
Convenience and ease of use have made the cam-type mechanism popular. But this is not without its disadvantages. One is the difficulty in working with small drill bits. Short workpieces can simply drop in. You can still fix it by putting the drill in a horizontal position, but you can’t put too much pressure on it while working. If another drill bit has been inserted in the drill, it can be removed by turning the adjustment ring in the appropriate direction. It is not always possible to do it by hand, that’s why there is a special key, which acts as a lever, increasing the force. By the way, to tighten the drill bit without a wrench is also not recommended. The larger the diameter of the drill bit, the more reliable should be fixing.
When buying a fastener make sure it is rubberized, so you hurt your hands less when you fasten the tool.
The second most popular fastener can be used without a wrench. It is enough to insert the drill bit and turn the lever, it can often be done with one hand. Drill fixing, which provides this type of chuck is enough for most jobs, but compared with the classic version of the attachment it is inferior in terms of reliability, and costs more. The main advantage of the quick-change chuck is the speed of drill changing and the safety of the process, because this chuck does not have teeth that can injure your hands. The absence of a specialized wrench is also a significant advantage! Experienced builders know how easily it gets lost, so very often you can see the key taped with duct tape or duct tape to the wire.
True, it does not add convenience, but it gives some confidence that you do not have to look for a key all over the site. How to Change a Drill Bit in an Electric Screwdriver? The scheme is absolutely identical. The chucks in most drills are similar to the fasteners on screwdrivers. Of course, the latter tool can not be a full-fledged replacement for a quality drill, if only because the fastener is not provided for drills with a large diameter, and the speed of the electric screwdriver, as a rule, is less.
How the drill bit is inserted into the drill
The procedure is very simple and performed quickly, and in the skillful hands of the master it can take a few seconds. However, a number of rules should be strictly observed to protect yourself from unforeseen events.
- First make sure that the power drill is disconnected from the mains.
- Choose a drill bit based on the nature of the work and the material to be drilled. It is also important to find out the compatibility of the consumable with the electric drill.
- Insert the drill bit into the chuck with the tip pointing inwards.
- Next, it must be fastened inside the chuck, based on its type. This can be done with the toothed wrench (toothed type) or by turning the socket manually (quick-action type).
- After fixing, make sure that it does not wobble, and that there is no backlash.
- You can now proceed directly to work.
Important! Before inserting the drill, it is recommended that the cams should be set to a margin, so that it is easier to install.
The selection of consumables depends on the power tool itself. There are a variety of models that differ among themselves in the variety of technical equipment and functionality. There are models that are not adapted for drilling metal, in other electric drills you can install nozzles with a diameter of 0.8-10 mm or 1.5-15 mm.
Now about the quality of the drills themselves. It is not recommended to buy cheap products, because they are made of low quality material, and therefore will not last long. It is better to pay more, but such drills will last a long time.
Setting the working tool on the rotary tool
As mentioned above, the torch must be checked for proper operation before installing the drill. To do this test, the operating mode of the torch is set to drilling without striking. If you can hear and feel the engine running smoothly and without shock after you press the start button, it means that you can use the torch for its intended purpose by inserting the drill bit or auger into it.
To mount a drill bit with a cylindrical shank in the peorator, use an adapter with a cam-type chuck
Before inserting the drill bit into the chuck, it is necessary to treat the shank of the working tool with a special grease, which will protect it from corrosion. The procedure for inserting the drill bit into the torch is as follows.
- Place the back of the torch on the floor or another hard surface.
- The sliding part of the clamping device is pulled back.
- Insert the tool as far as it will go into the torch. The drill or auger to be inserted into the torch must be held vertically. If this requirement is neglected, you may encounter the fact that the tool will fly out or even break, and this can lead to a failure of the rotary table itself.
Press until a gap is felt, then pull the drill bit, if it does not come out, all is well
Taking into account that the principle of operation of modern clamping cartridges is quite simple, there is usually no question about how to take the drill out of the torch.
After you have removed the used tool and replaced it with another one, it is advisable to immediately clean its shank of grease and construction dust. The drill shank that you are going to insert must also be cleaned and pre-lubricated. A tool replaced in this way will not damage the clamping mechanism of the pen and will last much longer.
The lubricant extends the working life of the auger and the rotary table
Using a peorator, you can not only get a drilled element of the construction, but also perform processing with a special chisel. It is also possible to install a mixer as a tool in such a device.
DIY enthusiasts often have questions about how to insert the drill into an electric screwdriver or how to change the chuck on the rotary tool. To solve the first question quite simply, because the design of an electric screwdriver uses the same chuck design as a drill and a peorator. But the question of how to correctly replace the chuck on the torch should be approached with knowledge: to perform such a procedure, without certain knowledge and skills, is not easy.
Sometimes craftsmen may have the question of how to insert the drill bit in an electric screwdriver, if the drill bit has a diameter less than the minimum allowable. If you want to make very small holes in radio components, plastic or metal, sometimes you have to use very small drill bits. And without additional tricks it is unlikely to be possible to clamp a drill bit of this size in the chuck.
The easiest way is to wind a thin copper wire (0.2 to 1 millimeter) on the tail of the drill. If you do not have any thin wire, you can strip the insulation from the stranded copper wire and remove one strand from it. Wind the wire very tightly with no gap. Cut the remaining length of wire.
One option in such a situation, wrap a piece of paper around a thin drill bit.
This will increase the diameter of the drill shank and ensure a firm grip in the chuck jaws.
Key chucks make it possible to fasten the drill in the clamps with a matching wrench. The wrench is a rod with a lever with a small toothed wheel set on the rod. On the chuck a hole is made for fixing the shaft of the wrench and a circular toothed bit corresponding to the profile of the wrench.
In order to clamp or unclamp the cams, you must enter the rod in the groove, put the gear on the teeth of the bit and rotate the wrench in the appropriate direction.
Usually all wrenches are identical and fit different tools, but there are exceptions. For example, some expensive brands make peculiar keys with individual dimensions and profile.
In any case, it is very easy to lose a wrench because of its small dimensions, and it is very difficult to insert and remove the drill without it. That’s why many craftsmen tie the wrench to the handle of the tool.
